Phones keep disconnecting since asterisk 11.20


Probably since the 11.20 asterisk update, phones in the same network as the server are randomly reported as “not registered”.

Totally stable before.
Now the PBX is updated to the latest available version (13.0.22) but still the same issue.
To reduce the impact, I reduce the registry expiration time on the phone to 60 sec.

Any help is welcome.

I switched from asterisk 11.20 to 13.6 and during the latest 8 hours phone connectivity was again stable.
To be con’t

probably liniked to that: “chan_sip loses registrations after a while” in version 11.20
